探討建模文本對於十年級學生學習原子模型之學習成效與建模能力之影響

Abstract

科學文本在學校科學教育中扮演著非常關鍵且重要的角色，不僅能夠幫助學生對於科學概念的學習，更是教師設計教學活動的主要依據。據此，本研究以建模歷程為架構設計了「外顯式」與「內隱式」的建模文本，並依照學生心智模式的屬性，將36位十年級學生平均分到「一般文本組」、「內隱式建模文本組」與「外顯式建模文本組」，最後，則透過各組科學文本的閱讀，探討學生對於原子模型概念、心智模式與建模能力的影響。本研究結果顯示學生在原子模型概念上，以外顯式建模文本的閱讀較有助於完整原子模型概念的學習，並能夠發展其建模能力，也能在閱讀文本之後，建立較接近科學模式的心智模式，因此，此結果也彰顯了外顯化建模歷程的效用，更顯示出外顯式建模文本的有效性，最後，也能在科學教育中提供建模科學文本編寫的參考依據。

Scientific texts played an important role in science education. They not only could help students to learn scientific concepts, but they were also the main basis for designing teaching activities by teachers. In order to investigate the impact of scientific text, this study used two modeling-based texts about the atomic model for high school students to learn the atomic models during different periods of time. One of them included explicit descriptions and representations of modeling process, and the other included implicit description of modeling processes. The participants of this study included 36 tenth-grade students from a high school in New Taipei City. The students were equally classified into three groups in which students read three different versions of scientific texts (i.e., two modeling-based texts and one regular textbook). Finally, this study investigated the effectiveness of reading three different versions of scientific texts, mental models and modeling competencies about the atomic models. The analyses results revealed that the students who read modeling-based text that including explicit modeling process not only had better learning performance about the concepts of atomic model , but they also developed better modelingcompetencies. Furthermore, the modeling-based text helped students construct their mental models closer to the scientific models. In sum, the results revealed the significant effects of the modeling-based text that including explicit modeling process, and it also provided a reference for the preparation of relevant textbooks.
